Generally, the flywheel rotor is composed of the shaft, hub and rim (Fig. 1). The rim is the main energy storage component. Since the flywheel stores kinetic energy, the energy capacity of a rotor has the relation with its rotating speed and material (eq.1). 1 2 2
Electrical energy is generated by rotating the flywheel around its own shaft, to which the motor-generator is connected. The design arrangements of such systems depend mainly on the shape and type
Compared with traditional electrochemical batteries, flywheel energy storage systems are attractive in certain aerospace applications due to their high power density and dual-use ability to achieve attitude control.

Flywheel energy storage or FES is a storage device which stores/maintains kinetic energy through a rotor/flywheel rotation. Flywheel technology has two approaches, i.e.
A flywheel energy storage can have energy fed in the rotational mass of a flywheel, store it as kinetic energy, and release out upon demand. They work by spinning up a heavy disk or rotor to high speeds and then tapping that rotational energy to discharge high power bursts of electricity. It is difficult to use flywheels to store energy for
Flywheel energy storage system is focused as an uninterruptible power supplies (UPS) from the view point of a clean ecological energy storage system. However, in high speed rotating machines, e.g. motor, generator and flywheel, the windage loss amounts to a large ratio of the total losses. The reason is that windage loss is

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of th
